Title: Electric hoist with emergency brake releasing device
Inventor: MOTOKI TOSHIO
IPC: B66C13/23
Filed: 1993-09-03
Abstract: PURPOSE:To let a cargo fall approximately at constant speed by actuating an operation button switch from the ground at the time of a power failure for releasing a brake force with direct current from a battery, and adjusting the moment of inertia with the mechanical loss of a brake rotor or the like. CONSTITUTION:A brake 16 is released to let a cargo fall, when a power failure takes place. Namely, a pushbutton is pressed to cause a DC solenoid to attract a brake lever 7 for the turn thereof. As a result, a brake rod 7 is pulled back against the force of a brake spring 4, and the pushing force of a brake disc 2 disappears. Thus, brake torque drops to zero level. In this case, a clutch gear rotating only at the time of a power failure, a gear 12, a brake rotor 11, a brake wheel 1 and the like act as resistance to rotation. (Namely, these act as a mechanical loss for retarding rotational acceleration.) Furthermore, the moment of inertia increases, when the weight of the brake rotor 11 is adjusted (i.e., change in diameter and thickness) and the cargo continues to gradually fall without any sudden acceleration.

Title: Tension measuring apparatus
Inventor: ONOE YOSHIFUMI
IPC: G01L5/10
Filed: 1986-09-19
Abstract: PURPOSE:T miniaturize the title apparatus and to enhance measuring accuracy, by a method wherein an article to be measured in supported so as to be pinched by a plate-shaped measuring member composed of an elastomer and two support members and the strain of the elastomer generated by the load of the article to be measured is detected to calculate the tension of the article to be measured. CONSTITUTION:An article 1 to be measured such as a belt or a chord is arranged so as to be pinched by a measuring member 3 and two support members 2 and the measuring member 3 is mounted on a mount member 4 by a fixing screw 8 through a spacer 7. Since stoppers 5 are provided to the support members 2, the article 1 to be measured is prevented from movement even in the state pinched by the support members 2 and the measuring member 3 and the strain of the measuring member 3 is detected by the detector 6 such as a strain gauge adhered to the measuring member 3. The tension of the article 1 to be measured is calculated from the relation between the strain of the measuring member 3 and the tension of the article 1 to be measured preliminarily formed.

IPC: H01L21/68
Filed: 1986-09-19
Abstract: PURPOSE:To detect the position of an alignment pattern by a method wherein the alignment pattern, which is arranged closely contacting between other patterns using the alignment pattern having specific periodicity, is distinguished from the patterns on the circumference after the configurational change of detected signal due to the change in focus position and the like has been tolerated. CONSTITUTION:The image information in two different directions is obtained from the image 1 containing the alignment pattern 2 provided on the objective substance such as a substrate and the like by an optical system and an image pickup means, the position of the alignment pattern 2 is detected from said image information, and the position of the objective substance is worked out from the result of said inspection. In the above-mentioned position detecting device for a substrate and the like, the alignment pattern 2 provided with a specific periodicity is used. As a result, the alignment pattern 2 can be distinguished from the other patterns 3 by selecting the modulated part, having the periodicity of the alignment pattern 2, from the waveforms 4 and 5 obtained by adding lengthwise and breadthwise the two dimensional image 1, and the alignment pattern 2 can be arranged adjoining to the circuit pattern and the like.

Title: Device for testing flash memory
Inventor: KOBAYASHI SHINICHI
IPC: G11C16/06
Filed: 1993-09-03
Abstract: PURPOSE:To shorten an erase testing time by using a signal AFAIL in which all flash memories to be erase-tested are failed and the signal OFAIL in which any memory is failed and controlling the sequence of the pattern generation. CONSTITUTION:After the erase operation is performed for the whole or a block of the flash memory MUT, an address is specified for a first address within an objective range. The normal/defective condition is decided by an output of a logical comparator 4. At the time of specifying the address, a pattern for deciding the address after the address is generated by a test pattern generator 2, and the normal/defective condition is decided continuously. The generated address and a loop count value used for generating the address are held until a decision result is returned from the comparator 4. Since only when the decision result is the AFAIL, the pattern for the erase operation is generated, a decision stand-by time at every one time is eliminated. Further, no test is performed for the address passing the normal/defective condition decision of the erase operation after a second time. Thus, the erase test time is shortened.

Title: Video signal decoder
Inventor: KASEZAWA TADASHI
IPC: H04N7/30
Filed: 1994-09-14
Abstract: PURPOSE: To reduce coded noise by giving a decoded image to a characteristic variable low-pass filter whose filter characteristic is decided based on the quantity of a quantization scale code. CONSTITUTION: A filter characteristic decision circuit 9a controls the pass band of a characteristic variable low-pass filter 8 to be narrow when the quantization scale code 109 is high and wide when the quantization scale code 109 is small. Thus, the coded noise of a decoded image 106 outputted from a decode image generating circuit 7 is reduced through the characteristic variable low-pass filter 8. A coefficient of a multiplier of the characteristic variable low-pass filter 8 is revised based on a filter characteristic designation signal 112 from the filter characteristic decision circuit 9a. Thus, the characteristic of the low- pass filter is changed.

Abstract: PROBLEM TO BE SOLVED: To avoid troubles that are caused when an A/D converter is continuously operated at a high speed by generating the time intervals related to the analog input voltage in response to this voltage and counting the time intervals related to a prescribed delay time by a time digitizer circuit. SOLUTION: A voltage to time converter 14 has a group 24 of comparators 26 to 30 and performs the clock operations of flip-flop banks 18 to 22 in response to a fact that the ramp voltage generated by a ramp generator 32 exceeds the input reference voltage.

Title: Torque control device for internal combustion engine
Inventor: MIURA SO
IPC: F02D13/02
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce torque in a high speed-low load area receiving restriction in reduction of torque by a minimum valve-operating period of an intake valve in non-throttle operation by providing the solenoid-operated intake valve and exhaust valve and by controlling the intake air quantity by controlling the opening period of the intake valve. SOLUTION: In a high speed-low load area, the valve opening timing of an exhaust valve is retarded behind the bottom dead center(BDC). Thus, by increasing the pump loss in the exhaust stroke, reducing the exhaust efficiency and suppressing the suction of fresh air by leaving residual gas in a cylinder, torque is reduced. Switching to angle of lag of spark timing, 8 cycle operation, etc., is used simultaneously to further reduce torque.

Abstract: PURPOSE:To contrive to decrease the number of heads by erasing in parallel recording areas of the inside and the outside of a disk by two heads at the time of recording, changing the head after the erasion and recording a signal in parallel. CONSTITUTION:Recording track erasion processings of recording areas 32, 34 of the inside and the outside of a magneto-optical disk 1 are executed in parallel. As for the area 32, since a downward external magnetic field by a permanent magnet 20 in a permanent magnet group 15B is utilized, the processing is executed by radiating a laser beam from a head 30. On the other hand, as for the outside recording area 34, since a downward external magnetic field by a permanent magnet 18 of a permanent magnet group 15A is made uniform in the magnetization direction, the processing is executed by radiating a laser beam from a head 26. When the erasing operation is ended, recording is executed by executing a tracking control so that the head 26 brings an erasing track of the area 32 to tracking control and the head 30 traces an erasing track of the area 34. The reproducing operation is executed by tracing a laser beam simultaneously to recording tracks of the area 32 and the area 34 by the head 26 and the head 30, respectively.
